Biovisus deploys a full cystoscopy system with rigid and flexible cystoscopes. Rigid models come in 4 mm diagnostic and 8 mm therapeutic sizes, paired with swapable Hopkins rod-lens telescopes offering 0°, 12°, 30° and 70° viewing angles. The flexible cystoscope has a 16 Fr tip, 6.5 Fr working channel, 180-degree two-way bending and a 120-degree field of view.

The rigid cystoscope sheath locks onto different angle telescopes with bayonet fittings. The 8 mm therapeutic sheath holds a channel for 7 Fr tools such as biopsy forceps, stone retrievers and injection needles. Its rounded atraumatic obturator enables gentle urethral insertion.

The flexible cystoscope has a 14 Fr shaft with graded rigidity. The front 5 cm stays pliable for bending, while the rear section stays firm for easy advancement. Its channel fits 5 Fr instruments. The handpiece has an irrigation port with one-way valve, and a control lever delivering direct 1:1 movement for full 180° deflection.

Both devices link to one unified urology imaging set: 300 W LED light source, 4K image processor and 32-inch medical monitor. A special cystoscopy color setting boosts contrast between healthy bladder lining and abnormal growths including papillary tumors and carcinoma in situ. Blue-light fluorescence cystoscopy is supported by matching excitation filters inside the light source and viewing filters on the camera head.

Technical Note: Check rigid telescope image quality before every procedure; dark curved shadows signal broken rod lenses needing replacement. Test tension on flexible scope bending wires monthly; over 10 degrees of delayed bend means stretched wires that need maintenance.

Biovisus provides single-use ureterorenoscopes for ureteroscopy and flexible nephroscopy. Single-use scopes eliminate infection hazards and reprocessing workload associated with reusable equipment, and multicenter tests confirm its optical quality performs equally well compared with premium reusable ureterorenoscopes.

The single-use ureterorenoscope is designed with an 8.5 Fr distal tip, 270° bidirectional deflection and a 3.6 Fr working channel, alongside a 120° field of view. It has a uniform 9.5 Fr graded-stiffness shaft. The ergonomic ambidextrous handle comes with a deflection lever, while the working channel opening is arranged at the 10 o’clock position for comfortable operation.

This scope connects to the image processor using a magnetic breakaway cable that separates under 5 newtons of pulling force to protect devices. Its tip-mounted digital camera produces 1920×1080 videos at 60fps. Built-in distal LED lighting removes reliance on external light sources, streamlining setup and lowering hardware failure risks.

The working channel accommodates 200–365µm laser fibers for lithotripsy. A PTFE inner lining prevents fiber binding during deflection. The ceramic-reinforced distal tip safeguards the camera against laser backfire. To enhance safety, the system lowers laser power by 50% automatically when deflection exceeds 250°.

Technical Note: The pre-sterilized ureterorenoscope should remain sealed right until usage and must be replaced once the package is damaged. The magnetic connector’s 5 N breakaway force is factory fixed. Manual fastening will disable safety functions and potentially damage the image processor port.

Biovisus customizes an irrigation pump optimized for urological surgeries. It supplies sterile saline with adjustable flow from 50 to 800 mL/min and regulated pressure between 30 to 250 mmHg. The default pressure caps at 80 mmHg for ureteroscopy to reduce backflow and postoperative sepsis risks, with real-time pressure data overlaid directly on the medical monitor.

The pump adopts a dual 3L fluid bag design for uninterrupted operation. It automatically switches to the backup bag once the primary bag runs empty and sends alerts for bag replacement. The built-in warming unit stabilizes fluid temperature at 37°C ± 1°C under 300 mL/min. Temperatures may decrease to 35°C at higher flow rates, which is safe for short-term stone removal procedures.

High-flow mode reaching 800 mL/min and 250 mmHg pressure is available for percutaneous nephrolithotomy. The matching rigid nephroscope features a 24 Fr sheath and 7 Fr working channel with optional 0° and 12° lenses. Compatible with shared light source and image processor, its large channel supports ultrasonic and pneumatic lithotripsy devices.

The system monitors irrigation input and output to calculate patient fluid absorption during PCNL. An alarm triggers once absorbed fluid surpasses 1000 mL, reminding clinicians to halt surgery and check for fluid overload symptoms. All irrigation related data is automatically saved to procedural reports.

Technical Note: Calibrate the pump pressure sensor at the patient’s kidney level to ensure accurate pelvic pressure readings. The nephroscope obturator needs to remain sharp; blunt tools raise dilation force and increase the risk of urinary tract damage.

Biovisus connects electrosurgical units to cystoscopy and ureteroscopy systems for bladder tumor resection and lesion removal. Special urology power modes include 100–200 W pure cut for tissue excision and 40–80 W spray coagulation to stop bleeding.

A 26 Fr continuous-flow bipolar resectoscope is used for bladder tumor surgery. It works with saline irrigation without grounding pads, preventing TUR syndrome. Built-in impedance sensing adjusts power automatically, supplying 180 W while cutting and dropping to 80 W at rest to prevent muscle twitching.

The cutting loop is spring driven and operated by thumb control. 12° and 30° lenses offer clear sight, and circulating fluid keeps bladder pressure stable at 30–50 cm H₂O. The irrigation pump runs at 300 mL/min with a maximum pressure of 100 cm H₂O for this procedure.

Disposable ureterorenoscopes fit laser fibers to treat upper urinary tract tumors. Holmium and thulium lasers run at 10–20 W coagulation settings to avoid tearing thin ureter walls. Laser settings and total energy use show on screen and save to patient files.

Technical Note: Check the resectoscope loop for deformation before each case. Bent loops lead to rough cutting and higher bladder tear risk. Trim laser fiber tips before use; worn tips lose nearly 40 percent power and can snap inside the scope.
